EFIELD MH-S-241 Angle Stainless Steel Water Hammer Arrestors, 3/4 Inch Swivel FHT x 3/4 Inch MHT (1)

Not for UK (EU?) washing machines. The washing machine hose fits correctly but when other end is screwed to the water tap or the washing machine it's still slack. Turn tap on, serious water leak. Reason; this is for hose connection ONLY, therefore washing machine hose fits fine but washing machine is not a hose connection, therefore leaks. Simple! This should be made clear in the listing description

Does what it says ok.

This water hammer arrestor does not fit British washing machine hoses. British hoses are 3/4" BSP (14 threads per inch); this device is 3/4" GHT (Garden Hose Thread, 11.5 threads per inch). GHT is used in USA and Canada but not in Britain. I sent these back and bought two Sioux Chief 3/4" BSP water hammer arrestors from Screwfix - they were more expensive than Amazon but they fitted my washing machine and dish washer hoses and did the job perfectly - no more banging pipes.

We had water hammer from our washing machine this product has stopped it so far.

Do not buy if you live in the UK this does not fit 3/4 BSP washing machine connections. Amazon should not promote this item in the UK. It is also shipped from the USA

Easy to install to the back of my Bosch washing machine, although had to use a spanner to tighten the supply hose to the unit (normally hand tightening should work but did not). While water hammer has not been eliminated completely, it has reduced.

Just gone to fit these but both are faulty, the female thread stops short inside fitting so not sealing on seal. Tried to return for replacement but can’t as over a month??

Had to send them back because US threads are not compatible with UK threads. I could screw them on but not tighten them. Why sell them to UK buyers?

Lo compre para usar en la toma de la lavadora (agua fria y caliente), tambien compre un medidor de presion para la tuberias. Las mediciones muestra que no hay ninguna diferencia de usarlos o no.

Easy to install! We had an obnoxious hammer. It seriously sounded like a hammer when the water stopped! It took about 5 minutes to get both arrestors on. I attached them to the washer instead of at the valve. It doesn't matter if it is at the valve or at the washer. I started a load of clothes and it was amazing!!!! No more hammer! I just installed today so I hope they last but the initial results are just amazing!

I've used this for 2 seasons now and it has eliminated the pipes banging when my sprinkler timer would shut off. Without this, the pipes would bang so loud it would wake the entire household. Now, the taps shut off and you don't even notice! I hope it lasts for a long time.

Very easy installation process (attached directly to the hot and cold inlets on my LG washer. This took care of the water hammer caused by the rapid opening of the solenoid valves that engage when the washer fills at the beginning of the cycle. The machine runs silently after the installation. Here is my only gripe - the packaging label is very ambiguous. In two places it says lead free and in a third it indicates a low lead content. Since I am not using this on a potable water line I was not too concerned about the ambiguity. It would be really great if the vendor would weigh in on this and indicate if this product is truly lead free - for peace of mind in potable water applications.

They have the wrong thread for Australian use, don't buy these.
